FAQs

What is the exact size of the window?

The address window measures 100mm in width and 45mm in height.

Where is the window located on the envelope?

The window is positioned 45mm from the left edge and 15mm from the top edge of the envelope.

How does the self-seal closure work?

The self-seal strip has a dry adhesive. Applying a small amount of moisture (e.g., a damp cloth or sponge) to the strip activates the adhesive, allowing it to bond securely when the flap is folded down.

What size paper fits best in a C5 envelope?

A C5 envelope is designed to hold an A4 sheet of paper folded once in half, or A5 sized documents without folding.

Are these envelopes suitable for mailing sensitive documents?

The 100gsm paper offers good opacity, reducing the chance of content showing through. However, for highly sensitive documents, consider using an inner envelope or a fully opaque envelope.

Can I use these envelopes with mailing machines?

These envelopes are generally compatible with standard office mailing equipment. However, always check the specific requirements of your mailing machine, especially regarding flap type and paper thickness.

What is the difference between this and the 90gsm version?

The 100gsm version is slightly thicker and more durable than the 90gsm version, offering better opacity and a more premium feel. The 90gsm version is lighter and may be more cost-effective for very large mailings.

Troubleshooting

Self-seal strip not adhering

Ensure a light, even application of moisture to the adhesive strip. If the strip has been exposed to high humidity or prolonged dry air, its tackiness may be reduced. Try a slightly more liberal (but still brief) application of moisture.

Address not visible through the window

Reposition your document within the envelope. Check that the address is printed within the correct area on your document (100mm x 45mm window, positioned 45mm in and 15mm up from the respective edges).

Envelopes sticking together in storage

This can occur if stored in humid conditions. Separate them gently. Ensure they are stored in a dry environment with good air circulation.

Pros and Cons

Pros

  • Durable 100gsm paper for a premium feel.
  • Self-seal closure for quick and secure mailing.
  • Standard C5 size accommodates common document formats.
  • Convenient address window saves addressing time.
  • Supplied in a bulk pack of 500 for efficiency.

Cons

  • Window placement may not suit all document layouts.
  • Self-seal adhesive requires a small amount of moisture to activate.
  • Only available in white, limiting color options.
  • Not suitable for extremely large or bulky contents due to C5 size.

Setup, Compatibility & Care

Setup: These envelopes require no setup. Simply insert your document, ensuring the recipient's address is positioned correctly within the window area (100mm wide x 45mm high, starting 45mm from the left edge and 15mm from the top edge). Moisten the self-seal strip along the flap and press firmly to close.

Compatibility:

  • Document Size: Compatible with documents up to C5 size (162 x 229mm). Best suited for A4 paper folded once.
  • Addressing: Ensure your mailing labels or printed addresses align with the window dimensions. Test print your documents before bulk insertion.
  • Mailing Systems: Generally compatible with standard postal services. Check with your postal provider for specific size or weight restrictions.

Care: Store envelopes in a cool, dry place away from direct sunlight to maintain the integrity of the paper and the adhesive on the self-seal strip. Avoid storing in humid conditions, which could prematurely activate the adhesive.
